INTRODUCTION* 



The study of mineral names is an interesting one, not only from the 
mineralogist's point of view, as affording an insight into the growth and 
development of this branch of science, but also to the student of human 
nature, for many traits of character are shown in the various considerations 
which have determined the particular name to be adopted. 

We sometimes find as the reason for a name the simple idea of distin- 
guishing the thing itself; but this is not the most common reason. To do 
honor to some person who may perhaps be pleased or flattered by the atten- 
tion, or to immortalize some place, often otherwise obscure or unknown, is 
a much more common reason. Names have been given to commemorate 
battle-fields, to sneer at the work of earlier investigators, and as a tribute 
to feminine loveliness. In short the whole round of human passions has 
been gone over in the manufacture of these words, which are purely scien- 
tific in their uses, and for the making of which scientific methods might 
well have been employed. The subject has also no little interest from the 
philological side, and these names deserve stady if only as part of our 
language. 

One of the most noticeable things about mineral names is the lack of 
uniformity in their terminations. While the large majority of them end 
in -ite, there are many in -ine, while -ane, -ase, -ose, and several others 
have been often used. It is to be regretted that the termination -ite has 
not been universally adopted, for it has been so far adopted as to be the 
generally accepted one for such names. It has the sanction of antiquity, 
for it was used by the old Greek writers in the forms -ites or -itis, as in 
ai/iariTTfi, 'hematite,' and dXa/Saaririi, 'alabaster.' Such forms were 
also used by the Romans, and we have in Pliny siderites, Modestone,* 
steatitis, 'soapstone,' molochites, 'malachite,' and many others. These 
forms are undoubtedly the source of the termination -ite now in use, as 
they are the earliest known terminations. Such names were given by the 
ancients as noting some property or use of the mineral, or sometimes desig 

* Much of this introduction is to be found in my paper on * The Origin and History 
of MinenUogical Names,* read before the New Yoric Academy of Sciences on January 
25, 1898, and published in vol. xi, pp. 49 to 57, of its Transactions.

nating its source, or the locality from which it was derived; as uayv^rts, 
a mineral from Magnesia. Or, to speak of those already mentioned, 
aiudrirrfS is a mineral resembling blood, so called from the color of its 
powder; dXaflaariTiS, a mineral from which a vessel called an alabastron 
was cut; siderites, from aidrfpo^, 'iron,' because it contains it; steatitis, 
from orearoS, *of fat,' because it feels greasy; and molochites, from 
ijiaXdxv* * mallows,' alluding to its green color. In the 5th edition of his 
great work on Mineralogy, Prof. J. D. Dana makes an attempt at uniform- 
ity of nomenclature by changing the terminations of many names into ite, 
particularly those ending in -ine, only leaving those unchanged which had 
come into too general use in the language to be so treated. So we have 
galenite, alabandite, pyrrhotite, and periclasite, instead of galena, alaban- 
dine, pyrrhotine, and periclase. These changes have been generally 
adopted, and are all in the right direction. 

In 1876 Prof. C. U. Shepard published a ' Catalogue of Minerals found 
within about 75 miles of Amherst College, Mass.,' in which he proposed 
that the names of all acknowledged mineral species, except those of the 
elements and a very few more, shall uniformly end in -ite, and that the 
termination -ine shall as uniformly be used for all variety names, and those 
whose specific character is not fully settled. Accordingly, he gives us 
gypsite, serpentite, wadite, orthoclasite, spodumenite, epidotite, and many 
similar changes, while marmolite, picrolite, nacrite, and others are made 
to end in ine, marmoline, picroline, nacrine. It is hardly necessary to say 
that these suggestions have not-been generally or fully accepted. 

The use of the termination -lite, in German -lith, from the Greek \iSoi, 
*& stone,' ought here to be mentioned, as it was a genuine attempt to intro 
duce a distinguishing mark for mineral names, which, if successful, would 
have been of great benefit to mineral nomenclature, as bringing in the 
desirable element of uniformity. This also comes from antiquity, being 
found in the Greek. But it never came into general use, and in later years 
is seldom used except for euphony. There is an erroneous impression 
that the termination -ite is derived from this, which, as we have seen, is 
not the case, as it is a much older form. 

As all scientific works were written in Latin up to a very recent date, 
and as there was no chemistry to show differences in composition, there 
was no real progress in mineralogy. External characters alone were used 
as means of distinguishing minerals from each other, and those that looked 
alike must necessarily be classed together. Pliny's names were sufficient 
for all the uses of the science down to the sixteenth century. There was 
hai-dly a name added, even by Agricola, whose large works were published 
1629 to 1546. The name fluor is perhaps his only new one, and that he

probably (lid not originate, but took from the vocabulary of the furnace- 
men, who used fluor-spar in smelting their ores. Certain minerals in general 
use had their common names in various languages, but there were few of 
them. 

Several attempts have been made to give systematic names to minerals 
on some such principle as is used in other branches of natural science, but 
not one of them has been generally ((Qopted, and all have by degrees been 
dropped. One of the earliest of these was by Sir John Hill, in his * History 
of Fossils,' London, 1748. He divides minerals into numbered series, 
classes, and orders, and under these into named genera and species. His 
genus names are many of them new, but are sometimes older names modi- 
fled to suit his system. For instance, Marmora, for the marbles. A good 
example of his new names, and also of the way tn which species were 
multiplied when only external characteristics were considered, is in the 
order of Inflammables. The 8d class is called Phlogonise, and under this 
we have as the 1st genus, Pyricubia, and under this two species: 1st, 
Pyricubium maximum foliaceum, and 2d, Pyricubium solidum minus. 
The flrst of these species is simply those cubical crystals of iron pyrites 
which are striated by an oscillation towanl a hemitetrahexahedron, and 
the second is the unstriated crystals of the same. Octahedral pjrrite is 
made another genus, and dodecahedral is still another. Several more 
genera are made trom what is now the one species. This system never 
came into general use, and Hill himself gives it up and adopts one much 
more simple in his later work entitled 'Fossils Arranged according to 
their Obvious Characters,' London, 1771. 

In 1820 Prof. Mohs brought out a small book entitled ' The Characters 
of the Classes, Orders, Genera, and Species; or the Characteristic of the 
Natural History System of Mineralogy. Intended to enable students to 
discriminate minerals on principles similar to those of Botany and Qeology.' 
This system is more fully presented in his larger work of 1822-4, trans- 
lated by Haidinger in 1825. He uses genus and species names for each 
mineral, and sometimes adds a third for more exact distinction. Under 
the genus garnet he gives Pyramidal Garnet, or idocrase; Dodecahedral 
Garnet, or true garnet; and Prismatoidal Garnet, or staurolite. Dioptase 
liecomes Rhombohedral Emerald- Malachite. This system was quite popu- 
lar for a time, and had several imitators. Prof. C. U. Shepard adopts 
Mohs's system, and in the flrst edition of his mineralogy, 1882-5, he not 
only uses his names, but extends the system still further. He, however, 
gives flrst the common or trivial names, as they are called, and always uses 
them in speaking of species. Microlite is the one new species of his own 
noted in this book, which under the system he calls Octahedral Tungstic- 



X INTRODUCTION 

'Baryte, and similar names are carried all the way through. None of these 
names are mentioned in his third edition, 1852-7. 

In 1836 Prof, J. D. Dana read a paper before the New York Lyceum 
of Natural History, entitled ' A New Mineral Nomenclature/ in which he 
presents a complete arrangement according to the Natural History method, 
and gives some very good reasons for its adoption. This system is carried 
out in full in the first edition, 1837, of his Mineralogy. He uses in general 
two names for each mineral, as Andalusius prismaticus for andalusite, but 
he gives the common name first in all cases. In his second edition, 1844^ 
he retains these Latin names as the scientific ones, and as necessary to * a 
systematic idea of the science,' but adds, p. 135, 'the shorter trivial names 
should however be retained, as more convenient for common use.' In the 
third edition, 1850. however. Prof. Dana discards the whole system, not 
even retaining the names as synonyms. A system of arrangement is 
adopted that was understood to be temporary, while at the end of the work 
a chemical classification is suggested. In the later editions this last has 
been perfected, and we now have an arrangement easy of reference and 
answering all purposes of classification, but from which all traces of the 
double Latinized forms of the Natural History methods have disappeared. 
This or some similar system is now generally followed by writers on miner- 
alogy, much to the satisfaction of those who use their works. In 1847 
Glocker published his work entitled ' Gtenerum et Specierum Mineralium 
Synopsis.' This is perhaps the most successful attempt at a systematic 
nomenclature that has been made. He uses in general a Latinized form of 
the common name for the name of each species, with some descriptive 
word added. For varieties he adds a third word, as is common in other 
branches of natural history. For instance, imder Granatus, garnet, he 
gives three species: 1st, Granatus nobilis, precious garnet; 2d, Granatus- 
hyacinthinus, cinnamon garnet; and 3d, Granatus vulgaris, common 
garnet, and under the latter he uses for varieties the terminations fuscus,. 
niger, viridis, flavus, and albidus. The work is in Latin, thus going back 
to the style of the scientific books of the last century. Recently Prof. T. 
Sterry Hunt has devised a new Natural System, suggested indeed as early 
as 1853, but as he. gives few new species names a discussion of it would be 
out of place here. His work is, however, exceedingly interesting, and will 
well repay examination by those who care to go further into that side of 
che general subject. 

In 1728 Dr. John Woodward published a work entitled ' Fossils of all 
Rinds Digested into a Method, Suitable to their Mutual Relations and 
Affinity,' but it is a description from external characters only, and can 
hardly be called a scientific treatise. The first one that really deserve8> 



INTRODUCTION 

such a name is by the Swedish mineralogist Wallerius, in 1747, which is 
arranged on a scientific plan, and gives us the earliest systematic descrip- 
tion of minerals. Cronstedt, another Swedish chemist, ten years later gave 
us a work of much greater value, as he brought in chemical relations, as 
far as was possible in the crude state of that science. But few new names 
were added, for the study was still largely from the external side, and new 
species could not be recognized. With the discovery of oxygen in 1776, 
and the real beginning of the science of chemistry, a more correct basis for 
the differentiation of mineral species was found. This was aided by the 
application of scientific crystallography, the first edition of de L'Isle's work 
appearing in 1772, and the second, in four volumes, in 1788. From this 
date new names were given to minerals as the result of more extended 
research in this branch of study, and one of the first of these was prehnite, 
given by Werner to a mineral brought from the Cape of Good Hope by 
Colonel Prehn, and hence named after him. Werner first announced the 
name in his lectures in 1788, as he himself states later, but it was not pub- 
lished for several years. In 1789 there is an article in the Journal de 
Physique, by Sage, objecting to the use of names of persons for minerals, 
the text for which is this name of Werner's. But the name has kept its 
place, and is now the accepted one for the species. Other names, given 
about the same time after persons, are witherite, after Dr. Withering, who 
first described it, and torberite, later changed to torbemite, after Torbem 
Bergmann, its first analyst. This latter mineral has gone through various 
vicissitudes as to its name, and a list of them, as an illustration, may not be 
out of place here; they are taken from the 5th edition of Dana's Mineral- 
ogy, p. 686: Mica viridis, 1772; Chalkolith, 1788; Torberite, 1793; Uran- 
glimmer, 1800; Torbernit, 1803; Uranite, 1814; Uranphyllit, 1820; Cupro- 
uranit, 1865. 

The author's study of the history of mineral names was begun in the 
interest of Murray's New English Dictionary, where these names are con- 
sidered as words simply, and part of the language as found in books. The 
information sought with reference to each is 1st, the author of the name; 
2d, the date of its first publication; 8d, a reference to the original publica- 
tion; 4th, its first form, if different from the one now used by English 
writers; 6th, its derivation; 6th, the reason for the name; 7th, a short 
description, sufficient to identify it, particularly if the name has been used 
for more than one species or variety. A good example is Erinite, a name 
given by W. Haidinger, 1828, Ann. Phil., 2d, iv, 154, from Erin, because 
it was supposed to have been found in Ireland. It is a green, fibrous, arse- 
niate of copper. This description is necessary to distinguish it from Erinite 
of 7. Thomson, 1886, Thom. Min., i, 342, derived also from Erin, for the 



XU INTRODUCTION 

same reason, and properly so, for it came from Ireland. But this is a 
reddishp clay-like mineral from the Giant's Causeway, and probably does 
not merit a name at all. 

Full information about many naiucs is easily obtained, and is usually 
to be found in the last edition of Dana's Mineralogy, up to 1892. But with 
reference to a considerable number of names the information wanted is not 
easy to obtain, and in some cases perhaps it cannot be found at all. When 
it is not given in Dana's Mineralogy, the student may be sure that he must 
search to find it. This is particularly true of obsolete names, information 
about which must often be sought in the earlier volumes of scientific 
journals. The first publication of T Taylar*B name killinite is in 1818, in 
vol. xiii, p. 4, of the Transactions of the Royal Irish Academy, a fact not 
given in any work on mineralogy. There are some names also about 
whi&h very erroneous ideas as to derivation prevail, and which need cor- 
rection. The name chabazite was given in the form chabasie, by Bosc 
d Antic, 1780, Jour. d'Hist., il, 181, and is derived from x^^P^^^o^* the 
name given to one of the stones mentioned in the Orphic poem ' Ilepi 
XiBov,* The name as we now have it in the poem is ;t^^<^Cto?, and the 
mineral should therefore have been called chalazite. Eidd called attention 
to the blunder in 1809, Eidd Min., i, 249; but the original name has held 
its place. It is but fair to say that the form x^flo^Z^oi was used in the 
current editions of the poem at the time the name was applied. The deri- 
vation of the word datholite has often been incorrectly given. It is really 
a corruption of the original name datolith, given by Esmark in 1806, from 
ddreojiicxt, to divide, alluding to the granular structure of one of its 
varieties, and Xtdoi. Werner added the h for no apparent reason, and the 
changed form was adopted by most authors until Prof. Dana, in 1868, un- 
riddled the matter and gave it its correct form again. But wise writers 
have tried to find another derivation for it, and one author of note says it 
is from ddBoi, which he says means turbid, because the mineral is not 
clear and transparent. A wiser one says there is no such Greek word as 
ddSoi, which is true, and that it is from the compound word da-BoXXoi, 
meaning very turbid, because it is never found in transparent crystals, 
which is no more a proper derivation than the other. The word feldspar 
has been changed into felspar for no better reason than that the latter form 
was thought the right one. It was used by Wallerius in his Mineralogy % 

of 1747, p. 65, in the Swedish form felt-spat, meaning fieldspar. It did not 
originate with him probably, but may have been a popular name in his time. 
Da Costa used it in 1757, Nat. Hist. Fossils, 287, in the German form feld- 
spath, and this form was current until 1794, when we find in Eirwan's 
Mineralogy, vol. i, p. 817, the following note: 'This name seems to oe 



INTRODUCTION xiil 

deriyed from fels, a rock, it buing commouly found ia granites, and not 
from feld, a field; and hence I write it thus, felspar.' This assumption of 
Eirwan has been taken for fact by all English writers, and the corrupt 
form is in very general use. Another interesting cose is that of the name 
pyroxene, which is popularly supposed to have been given, from nvp, 
*fire/ and ^dvoi^ 'a stranger,' in the idea that it is of mre occurrence 
among volcanic rocks, while in fact Hntly expressly states, 1801, HaQy 
Min., ii, 64, that it is very abundant among the volcanic matters of Vesu- 
vius, Etna, etc., but is there as a stranger, the name expressing that it 
is not in its native place, but existed in the nou-volconic rocks which 
furnished the original material of the lava. 

Authors often omit giving the reason for adopting a name. Where it 
is on account of some characteristic of the mineral, its author often takes 
it for granted that it is as evident to others as to himself. The name 
coracite, J. L. L$ Conte, A. J. S.. 2d, iii, 117, is a case in point. Le Conte 
does not give any derivation, but it is the name of a pitch-black variety of 
uraninite, and is probably derived from Kopa^, a raven. A similar case is 
that of adinole, Beud. Min.. 1882, ii, 126. No derivation is given, but it 
may easily be conjectured from the description that it is from ddiyoi, * com- 
pact.' But there are other cases where there is nothing suggestive in the 
description, and even conjecture is at fault. Such conjectures if stated as 
such are of value, but to give them as facts, as has often been done, is cer- 
tainly a serious blunder, if not something worae. In one of the large dic- 
tionaries we find the name acanticone derived as follows: from 'Greek 
ctK^, point, drri, against, and kSvo?, cone.' This is a mere guess. The 
name was given by B, J. d'Andrada, 1800, Jour, de Phys., ii, 240, in the 
form akanthicone, and is derived from txK(XvbU, a gold-finch, and kovux, 
powder, because the color of the powdered mineral is yellow. A similar 
blunder is made with the name alvite, so called after one of its localities, 
Alve, Norway. lu the dictionary it is said to be derived from alvus, 
the belly. Another instance of a mistaken derivation is that of coreite. an 
obsolete synonym of agalmatolite, popularly supposed to be from Corea, 
probably because agalnutolite is from China, and Corea is close by. , The 
name was given by J, C. Delamet^ierie in 1795. and he derives it from 
Xoipeioi, ' of a swine,' because of its greasy appearance. He at first calls 
it koireiite, but changed it to koreiite, and then to koreite, which has since 
been changed to its present form, resembling one derived from the name 
Corea. But the name should be choireiite, commencing with eh. 

Sometimes errors of the compositor have failed of correction, and these 
spurious words have found their way into later books as real names. One 
of these is glorikite, 1859, Duf. Min., iii, 826, which is an error for glinkite. 



XIV INTRODUCTION 

Gibsonite, in the 1847 edition of tbe same work, iii, 761, is probably an 
error for gibbsite, but this is not so clear. Gkiladsite, galadstite, and galad- 
tite are all printer's errors for galaktite. 

A curious case of this sort is seen in the various forms of the word 
didymite. It was announced by G, E. Schaufhautl in 1843 from didv/iios, 
a twin, because it was thought to be a second silicate containing calcium 
carbonate as part of its composition. The form was by some blunder given 
as didrimite, but this was soon changed by the author himself to the cor- 
rectly derived form, didymite, the original v being properly changed to y. 
Of this word you will find in the books four different forms, only one of 
which deserves any place in mineralogy. 

Breithaupt gave the name kupholit, from xov<po?, light, and \iBoS, to 
a very light variety of serpentine. He leaves out the o of the original 
word, probably because the word koupholite had been used before, being 
an obsolete synonym of prehnite. This was first changed to kuphoite and 
then to cyphoite, which gives little idea of its original derivation and 
meaning. 

Many more instances might be cited, but enough has been said to show 
how much confusion has arisen through carelessness or unwarrantable 
assumption, and how desirable it is that it should be disentangled as far as 
possible. 

In this work the endeavor is made to give complete information, as 
outlined above, concerning all the names that have ever been introduced 
into the nomenclature of Mineralogy. Nearly all published works on this 
subject have been searched to prepare a complete list of such names, and all 
available sources of information have been consulted. Many facts have 
been received in private communications from correspondents at home and 
abroad,, a list of whose names is appended. But a number of blanks still 
remain, after years of research, and the author greatly desires information 
on any of the points lacking. 

A number of personal names are not given in full. The use of the 
surname only has been common with foreign writers, and in some early 
cases it is perhaps now impossible to complete them. One of these is that 
of Uttinger, author of the name natrocalcite. A recent and very re- 
markable case is that of the late Adam, of Paris, author of the * Tab- 
leau Mineralogique,' Paris, 1869, and an honorary member of the Societe 
Mineralogique de Prance at the time of his death in 1881. The most per- 
sistent effort has failed to disclose his full name. In answer to a letter of 
inquiry on the subject the venerable Prof. Des Cloizeaux, his life-long 
friend, says: ' M. Adam est mort tr^s vienx, laissant une reniarquable 
collection de mineraux ^ I'Scole des Mines de Paris. II a toujours occupe 



INTRODUCTION XV 

de hautes situations au Ministdre des Finauces et personne, & ma coDDais- 
sance, n'a jamais connu »on ou sm prenoms. C'diait Monsieur Adam et 
cela sufflsait & tous ceux qui Tont connu.' 

Words have not been inserted under every change of spelling, but only 
those necessary to a complete understanding of each case. Some of the 
variations between c and k, i and y, and e, 8 and t have been omitted. 
>l either have forms in other languages been included where they are 
simple translations of the English names. Chemical names are also left 
out, except such as have the sanction of use as actual mineral names. By 
this means the number has been kept down to the four thousand six hundred 
and twenty-seven names here given, without omitting, unless by oversight, 
any that should be found in a work of this character. 

Following the Dictionary proper is an Index to the Authors of Mineral 
Names, which it is believed will be found of interest, as showing just what 
names each one has given. It has been found exceedingly useful in the 
preparation of this work.

In addition to ordinary and well-understood abbreyiations the follow- 
ing special ones are here used: 

f.. . • • from, referring to deriTatioD.

In the abbreviated references ordinal numbers refer to series, Roman 
numerals to volumes, and Arabic naraerals to pages unless otherwise 
stated. Numbers or letters in parenthesis mean parts, and the numbers 
immediately following the authors' names, which are always in italics, are 
the dates. If the original reference has not been accessible, it is enclosed 
m brackets, and a second reference which has been verified follows im- 
mediately. Where the original form of the name differs from its present 
English form, it is given in parenthesis immediately after the reference. 
Thus: 'MOROZITB. P. C. Abildgaard, [1798, Moll Jahrb., ii, 482]. 
1803, Reuss Min., ii, (2), 349 (Moroxit),' means that the name Moroxite was 
given by Abildgaard in 1798, and first appeared in von Moirs JahrbUcher 
der Berg- und Httttenkunde, volume ii, page 432, according to Reuss' 
Lehrbuch der Mineralogie, 1802, volume ii, part 2, page 349. where it is
